Which IEEE standard describes wireless communication?

802.11b

You are troubleshooing a wireless connectivity issue in a small office. You determine that the 2.4 GHz cordless phones used in the office are interfering with the wireless network transmissions. If the cordless phones are causing the interference, which of the following wireless standards could the network be using? (Select two.)

802.11b Bluetooth

You are designing an update to your client's wireless network. The existing wireless network uses 802.11b equipment; which your client complains runs too slowly. She wants to upgrade the network to run 54 Mbps. Due to budget constraints, your client wants to upgrade only the wireless access points in the network this year. Next year, she will upgrade the wireless network boards in her users'' workstations. She has also indicated that the system must continue to function during the transition period. Which 802.11 standard will work best in this situation?

802.11g

You have been contacted by OsCorp to recommend a wireless Internet solution. THe wireless strategy must support a transmission range of 150 feet, use a frequency range of 2.4 GHz, and provide the highest possible transmission speeds. Which of the following wireless solution would you recommend?
